The word "Phrenograph" is spelled with a combination of phonemes that can be transcribed using the International Phonetic Alphabet (IPA). The first syllable "phreno" is pronounced with the ˈfɹɛnoʊ sound, while the second syllable "graph" is pronounced with the ɡɹæf sound. Together, the word is pronounced as freh-noh-graf. The term "phrenograph" refers to the measurement of the skull in relation to mental functions, which was a popular theory in the 19th century.
A phrenograph is a device or apparatus that is used to measure or assess aspects of an individual's character or personality based on the shape and size of their skull or cranium. The term is derived from the words "phrenology," which is the study of the shape and size of the skull to determine mental traits, and "graph," referring to the process of recording or documenting such traits.
The phrenograph typically consists of a specialized instrument, often resembling a headrest, which is designed to secure the head in a fixed position during the assessment. Attached to this device are various measuring tools, such as calipers or other types of precision measuring devices, which are used to obtain accurate measurements of the skull's features and form.
The measurements taken by the phrenograph are then typically analyzed and interpreted by a phrenologist or practitioner familiar with the principles of phrenology. Based on the findings, certain traits or characteristics, such as intelligence, temperament, or even potential criminal tendencies, may be attributed to the individual.
Notably, the practice of phrenology and the use of phrenographs have largely fallen out of favor within the scientific community. Modern understandings of neuroscience and the complex nature of the brain suggest that it is not possible to accurately determine an individual's character or personality traits solely based on skull measurements.

The word "Phrenograph" is derived from the combination of two roots: "phreno-" and "-graph".
The root "phreno-" comes from the Greek word "phrēn" (φρήν), meaning "mind" or "brain". In Ancient Greek philosophy, "phrēn" was used to refer to the seat of consciousness or intellectual activity. This same root is found in words like "phrenology" (the study of the shape and size of the skull as an indicator of mental capacities or character traits) and "phrenic" (relating to the diaphragm or mind).
The second root "-graph" comes from the Greek word "graphē" (γραφή), meaning "writing" or "drawing". This root is commonly used in English to form words associated with writing or recording.
